9.3.1. Output mode

NOTICE!

Ensure that the connected loudspeaker type corresponds to the

actual output configuration of the D80.

Dual Channel mode (A/B, C/D)

The Dual Channel mode is dedicated to d&b fullrange systems

(passive systems) and actively driven d&b subwoofers. Both

channels of each pair of amplifier channels can be configured for

TOP or SUB cabinets independently.

In Dual Channel mode each pair of amplifier output channels

(AMP A/B, AMP C/D) acts as a two channel amplifier (stereo

amplifier). The amplifier channels are connected to their

corresponding output connectors (AMP A to OUT A ...) while the

audio input for each amplifier channel can be assigned via the

input routing.

Each output connector is wired in parallel using the respective pins

for TOP or SUB configurations.

Pin equivalents of NL4 and EP5 connectors in relation to the output

mode are listed in the table below.

NL4

SPEAKER OUTPUTS A (B, C, D):

1+/2+ = Amp A (B, C, D) pos.

1—/ 2— = Amp A (B, C, D) neg.

EP5 SPEAKER OUTPUTS A (B, C, D):

1/3 = Amp A (B, C, D) pos.

2/4 = Amp A (B, C, D) neg.

5 = n.c.
